St. Paul, MN Attention: Ms. Ashley Corbeille RE: 2017 THIRD QUARTER REPORTING PERIOD INFORMATION AND SEPTEMBER SAMPLING RESULTS SMRs INDUSTRIAL DISCHARGE PERMIT NUMBER 2289 SOUTHEAST PUMP AND TREAT SYSTEM CANADIAN PACIFIC SHOREHAM FACILITY Dear Ms. Corbeille: On behalf of Canadian Pacific, enclosed is the 2017 Third Quarter Reporting Period Information -SMR and September 2017 Sampling s-smr for the site located at 28th & Central Avenue NE. Minneapolis MN. In accordance with the Metropolitan Council Environmental Services (MCES) Industrial Discharge Permit Number 2289, effective October 1, 2016 (MCES permit), this submittal documents the volume and quality of water discharged from the groundwater pump and treat system owned by Canadian Pacific. The total quantity of water discharged into the sanitary sewer system during this reporting quarter was 975,840 gallons. The average daily discharge for the system was 10,607 gallons. Required information for the discharge is provided as follows: Attachment A - Reporting Period Information - SMR. Attachment B - Sampling s - SMR Attachment C - Analytical data from for the September 2017 monthly sampling event. Attachment D - Field Instrument ph calibration record. Analytical results from the September 2017 sampling event 1 showed that the treated discharge water was in compliance with the MCES permit discharge limitations during this reporting period. 1 Note that in addition to the required sampling for sample point SP-01 (identified as sample SE EFFLUENT in the attached lab report), Canadian Pacific voluntarily samples groundwater from the five recovery wells (RW07-39-SP, RW07-40-SP, RW06-28-I, RW07-38-I, RW06-27-BR) on a quarterly basis. All analytical data is included in Attachment C; only the required discharge data is included in the Sampling s - SMR in (Attachment 8). Golder Associates Inc West County Rd.
